Over 90% of modern people suffer from breathing problems. The common problems include chest breathing, mouth breathing, and hyperventilation (increased minute ventilation), all of which reduce oxygen levels in body cells and promote chronic diseases.

Note that advanced stages of asthma can lead to lung destruction, ventilation-perfusion mismatch,
and arterial hypercapnia causing further reduction in body oxygen levels.

The situation with automatic breathing in ordinary people is slightly better, but much worse than it was during first decades of the 20th century.

"Hence, normal breathing corresponds to a healthy organism" Dr. K. P. Buteyko, Dr. Buteyko's Lecture in the Moscow State University on 9 December 1969.
